[0059] Optionally, the first electronic wire group 332 may further include a ground wire and an aramid reinforcement yarn. The ground wire may be configured to connect to the earth, a shell or a wire with a zero reference potential. The aramid reinforcement yarn may be a thread made of high-density fibers.

The cable core layer 33 may include at least one aramid reinforcement yarn. Specifically, the cable core layer 33 may include three aramid reinforcement yarns. The at least one aramid reinforcement yarn may be twisted together with the coaxial cable, the first electronic wire group 332, and the second electronic wire group 333 to form the cable core layer 33. Therefore, pull resistance of the data cable can be improved by arranging the aramid reinforcement yarn and the ground wire.

[0060] Therefore, by selecting a cable core thinner than a conventional cable core, the data cable can have a smaller diameter and a lighter weight on the basis of meeting audio and video transmission bandwidth requirements. Moreover, the first electronic wire group and the second electronic wire group are both wrapped with shielding layers, so that anti-interference performance of the data cable can be improved.

When the terminal body is connected to the multimedia device, the switching module is connected to the multimedia module, and therefore audio and video transmission between the multimedia module included in the terminal body and a display screen including an HDMI can be implemented. Since the switching module is connected to the communication module when the converter communication interface is connected to the smart glasses, communication between the terminal body and the smart glasses can be implemented through the converter. Therefore, according to the terminal assembly for split smart glasses, the smart glasses can be in USB communication with a terminal when connected to the terminal through an HDMI converter, thereby reducing the number of interfaces in the terminal, to reduce the probability of damage to the terminal device.BRIEF DESCRIPTION OF DRAWINGS

The insulating layer included in each second data wire may be made of a perfluoroethylene propylene copolymer. The insulating layer included in each second data wire has a thickness of 0.07 mm.

[0056] In some embodiments, the first electronic wire group 332 can be used as a central part of the data cable 3. The coaxial cables and the second electronic wire group 333 can form a wrapping part around the first electronic wire group 332. Specifically, as shown in FIG. 4, the coaxial cables and the second electronic wire group 333 are located at the outermost part to wrap the first electronic wire group 332.

[0057] Optionally, a sum of thicknesses of the winding layer 32 and the outer cover layer 31 may range from 0.2 mm to 0.4 mm. A diameter of the cable core layer 33 may range from 2.0 mm to 2.2 mm. Through the winding mode and wire selection of one or more of the above-mentioned embodiments, while transmission performance and an anti-interference capability of the data cable 3 are ensured, the total diameter of the data cable 3 may range from 2.4 mm to 3.0 mm, preferably 2.6 mm to 2.8 mm, while the thickness of a conventional similar data cable is usually in a limit range of 3.5 mm to 3.8 mm. Therefore, through the data cable of one or more embodiments of the present disclosure, portability of the data cable and comfort of a user during use can be improved while performance of the data cable is maintained.

[0058] Optionally, outer rings of the first electronic wire group 332 and the second electronic wire group 333 may be both provided with metal shielding layers. In an example, the metal shielding layers may be made of aluminum foil. Specifically, the outer ring of the first electronic wire group 332 may be wrapped with a metal shielding layer. The outer ring of the second electronic wire group 333 may also be wrapped with a metal shielding layer.

[0059] Optionally, the first electronic wire group 332 may further include a ground wire and an aramid reinforcement yarn. The ground wire may be configured to connect to the earth, a shell or a wire with a zero reference potential. The aramid reinforcement yarn may be a thread made of high-density fibers. The ground wire and the aramid reinforcement yarn may be twisted with the first power wire, the second power wire, and the two first data wires to obtain the first electronic wire group 332. The cable core layer 33 may include at least one aramid reinforcement yarn. Specifically, the cable core layer 33 may include three aramid reinforcement yarns. The at least one aramid reinforcement yarn may be twisted together with the coaxial cable, the first electronic wire group 332, and the second electronic wire group 333 to form the cable core layer 33. Therefore, pull resistance of the data cable can be improved by arranging the aramid reinforcement yarn and the ground wire.

[0060] Therefore, by selecting a cable core thinner than a conventional cable core, the data cable can have a smaller diameter and a lighter weight on the basis of meeting audio and video transmission bandwidth requirements. Moreover, the first electronic wire group and the second electronic wire group are both wrapped with shielding layers, so that anti-interference performance of the data cable can be improved.
